Questions and Answers

What does the layout of columns mean in the context of a skeleton building system?

The methods of columns distribution in building and calculate amount of reinforcement in skeleton system.

What is the difference between how columns are distributed in skeleton systems and load-bearing walls systems?

In skeleton systems, columns are distributed in different ways and private systems, completely different from the system of load-bearing walls. In load-bearing walls system the amount of reinforcement differs from one space to others, but in skeleton system is different.

    Column Distribution in Skeleton Systems

    Methods for arranging columns in buildings using a skeleton system, different from load-bearing wall systems.

    Load-Bearing Wall System

    A building system where walls bear the main loads of the structure, leading to varied reinforcement amounts.

    Skeleton System

    A building system where columns and beams support the structure, with reinforcement dependent on column layout.

    Study Notes

    Column Distribution in Skeleton Systems

    • Column distribution methods vary significantly in buildings with load-bearing walls versus skeleton systems.
    • Load-bearing wall systems' reinforcement depends on the dimensions of each space.
    • Skeleton systems' reinforcement depends on the column layout type.
    • Columns are positioned in fixed axes in both directions, allowing beams to rest directly on them.

    Column Distribution Priorities

    • Architect and design team determine the type and shape of columns (e.g., square, rectangular, circular).
    • Columns are ideally placed at wall intersections to reduce secondary supports.
    • Columns should be positioned along a single axis for easier implementation and reduced errors.
    • Column positioning must follow architectural plans, avoiding interior spaces.

    Column Orientation and Spacing

    • Columns should be oriented along the building's long axis to avoid interfering with doors, windows, and other elements.
    • Placing columns at each building corner is often preferred.
    • Column spacing should be economically sound, balancing the costs of above- and below-ground project components (3–7 meters).
    • Larger bridge distances lead to greater iron costs, so the spacing needs balancing.

    Shear Walls and Column Integration

    • Shear walls (reinforced concrete walls) are sometimes used in skeleton systems to distribute forces effectively.
    • Shear walls are often positioned on both sides of elevator shafts and stairwells to reduce building damage risk.
    • Shear walls and columns should integrate well into the building design to optimize performance.

    Column Layout Types

    • Equal Distances: Columns are spaced equally in both directions (longitudinal and transverse), leading to similar spaces. This design is simplest in terms of planning and design.
    • Unequal Distances: Columns are positioned at different distances in both directions. The resultant spaces will have consistent areas, resulting in a consistent structural design.
    • Unequal Distances in One Direction: This layout adds complexity as spaces need customized designs to accommodate the variation in distances between columns.
